Configuring the Open Shortest Path First Protocol (Version 2)
– 747 –
Normally, only one key is used per interface to generate authentication
information for outbound packets and to authenticate incoming packets.
Neighbor routers must use the same key identifier and key value.
When changing to a new key, the router will send multiple copies of all protocol
messages, one with the old key and another with the new key. Once all the
neighboring routers start sending protocol messages back to this router with
the new key, the router will stop using the old key. This rollover process gives
the network administrator time to update all of the routers on the network
without affecting the network connectivity. Once all the network routers have
been updated with the new key, the old key should be removed for security
reasons.
Before setting a new key identifier, the current key must first be deleted on the
Show MD5 Key page.
